+# NEW FUNCTIONS IN FEIDLAMBDA v0.1
+
+FUNCTIONS FEIDLAMBDA v0.1:
+
+- `feid.utils.REPEATCOLS`: Mengulangi _vector_ sebanyak _n_ dalam bentuk kolom. RETURN: COLUMN VECTOR.
+- `feid.utils.SORTCOLS`: Menyusun ulang setiap kolom, berdasarkan _header_ yang diurutkan. RETURN: ARRAY.
+- `feid.utils.REPEATROWS`: Serupa dengan `.REPEATCOLS`, mengulangi _vector_ sebanyak _n_ dalam bentuk baris. RETURN: ROW VECTOR.
+- `feid.utils.RESHAPECOLS`: Mengubah dimensi array dari dimensi _rows x columns_, menjadi _rows x nsplit_ tanpa mengubah susunan baris array. RETURN: ARRAY.
+- `feid.utils.FINDINDEX2D`: Mencari index suatu elemen dari _array_ dengan keluaran berupa urutan elemennya, posisi baris dan kolom. RETURN: ARRAY / ROW VECTOR with {number element; index row; index column}.
+
+
+## REPEATCOLS
+
+```=feid.utils.REPEATCOLS(vector, [num_repeat])```
+
+Catatan: Jika `num_repeat` tidak diisi, maka secara _default_ bernilai 2.

+
+## SORTCOLS
+
+```=feid.utils.SORTCOLS(table, table_header)```
+
+Catatan: Jika input table sebagai array, maka pastikan memisahkan antara header array dan isinya.
